Plastic surgery Perth twins diagnosed with body dysmorphia

Perth twins Anna and Lucy DeCinque, who have spent a quarter of a million dollars on plastic surgery to look identical, say they regret how much they've spent and have been diagnosed with body dysmorphia.

The 31-year-old twins have spent $250,000 on their pursuit for perfection, which includes plumping their lips, tweaking their smiles, tattooing their eyebrows and getting breast implants.

It has taken them to the US, where they recently featured on E! Network reality series Botched in a bid for even more plastic surgery.

But the pair have now revealed they were recently diagnosed with body dysmorphia.

Clinical psychologist Sally-Anne McCormack believes up to two percent of the population are likely to suffer from the disorder.

"What it is is that constant worrying about either perceived or real flaws, or defects in appearance. So it can often lead to people grooming too much or looking at their appearance during the day," Ms McCormack told A Current Affair.

The DeCinque twins say they are ashamed of what they did to themselves, but are owning it and embracing their diagnosis.
